To all whom t may concern.' j

Be it known that I. GEORGE FOSTER Rnz- Non. a citizen of the United States, residing at Mercer, in the county of Mercer and State of Pennsylvania, have invented new and useful Improvements in Radiant Stoves, of which the following is a specification.

My invention relates toradiantstoves.

One object of this invention is to provide a radiant stove or fireplace which is attractive inl appearance, simple in construction, easily repaired` and relatively cheap tornanufacture. Another object is to provide a novel mounting for the back wall whereby it may be readily inserted and removed without the use of special fastening devices. I provide also novel means for holding the radiante vertically and for preventingI the overheating of the wall of a room close' to the back of the stove. I provide also a novel means for mounting'the mixing tube Sothat by the removal of a single screw or bolt the burner tubes together with the mixing chamber carrying the same may be readily re moved. Other objects appear hereinafter.

Referring to the accompanying drawings, Fig. 1 is a front view of one form 'of my invention, the radiante on the right-hand` side being' omitted; Fig. 2, a section taken on the line yII-II of Fig. 1; Fig. 3, a frag,-

' mentary view showing the rightlhand` 'parts in front elevation and theleft-hand parts in vertical section; Fig. 4l, a plan view of Fig. 1 with the hood omitted and the back plate or jacket in horizontal section; Fig. 5, a section on the line V-V of Fig. 4, back wall omitted; Fig. 6, a sectional detail showing the manner of mounting one of the front legs; Fig. 7, a detail view showing the manner of supporting the right-hand end of the mixing tube: Fig. 8,a bottom plan view of the hood; Fig. 9,/ an end view of the hood; Fig. l0; a fragmentary elevation of the back wall; Fig. 11,'a vertical section through the back wall and onefof the radiante; Fig. 12, an enlarged front elevation of one of the radiante. I

On the drawings, 1 and 2 represent'respectively front vand rear metallic vtrame members, the'l front member comprising a` horizontal plate of metal with rearward flanges 3 and 4 at its edges. VThe ends 5 of the frame member 1 curve forwardly and terminate in the flanges 6 parallel with the front of the stove. To the front of each flange 6 is secured by a single screwS the 1923. Vserial No. 649,695.

upper vertical member 9 of a leg 10 havingtwo lspaced feet 11, the screw extending through the iiange 6 and into the leg-member l() and serving as apivot on which the leg may adjust itselfso that both feet 11 will rest on an uneven tiled hearth, floor or other support. n

The rear frame member 2 comprises a casting 12 and a pair of hollow posts or columns 13 secured tothe ends of the casting by screws 15. which extend ythrough the yend walls 17 of thecasting and into lugs 16'integral with the inner face of the legs.l The columns are flush with the ends ofthe cast ing 12. ATher frame member 2 has the: forwardly projecting end portions 18 (only one shown) having each a kflange 19 (only"- one shown), through which a screw 2O passes theprojecting portions of the member 2 be# ing inclined downwardly to meet the upper edge of the member 1. A metal cover plate 27 extends from the forward 'faces of the columns 13 and theupwardly extending flange 28 vjust in front of the openings 25, down over 'the upper edge of thev frame member 1, and its ends reach'y about to the beginning of thecurved portions The bracket 29 is secured to the back wall 22 bythe screws 30 and has the lug 31' which carries-the gas jet or nozzle 32. which projects into the air mixing tube 33, having on its upper face theA gas jets or' burners 311 which project into the openings 25. The latter are of' such sizeasto 'allow the tube" 33 to belmoved slightly longitudinally; The lower side ofthe 'upper member 35 of the tube 33 has a thin depending lug or leg 36 which rests on the upper edge of the bracket 29, a finger 37 dependingV from the leg 36 and `engaging the'inner facel of the bracket the frame and against the end of a socket 39 in the end of the tube 33 as shown in Fig.

The screw `supports the adjacent end operating the valve.

ofthe mixer tube and also holds it--in its normalrposition. By removing the screw, the mixer tube with the burnersv may be readily removed. 4lis the gas-valve Aforthe nozzle 32, and 40 is the usual hand shaft for vThe columns l?)V have openand their tops -are closed by the revmovable caps 42 secured in place by the screws 43. Thel vertical hollow spaces in the columns are guides and retaining mem# bers for the back-wall 44 and the hood 45, composed of-any highly refractory material suitable for the purpose required. This material may be fire-clay or other compositionsA well known for the purpose intended.

The back-wall has vend portions 46 whichV slide down inthe columns. The main portion of the back-wall ,stands back somewhat froni'tlie guide portions 46 so that its front face is slightly back of the openings 25. This front face carries a number ofvertical e ribs 47, one back of the center of each opening' 25, and also other vertical ribs 48 between adjacent ribs 47. y l

l provide a number of verti-cal'radiants 49, each hollow and provided with a numberI of openings 50. The radiante are open at their lower ends, one radiant being seated over,V each opening 25. Each radiant has afvertical recess 5l in its' back to receive one 'of the ribs 47. The upper part of the .front face of the back-wall 44 slants up'-v wardly and rearwardly and the tops of the.

Vradiants standopposite this slanting Pay, andl are provided with closed tops, but their i rear walls are provided each with an openingvor vent 52 through which the heat and' productsofv combustion pass on their way*v to the notch 53 in the top lof the back-wall.

Y Thefribs 48 provide ventilation between the radiantsand the back-wally 44.A l i Theihood y45 rests upon the upper edge -of the back-wally 44 and has end guiding 'lugs 54 slidable 'in the columnsrl, rlhe front of the hood lies infront ofthe upper ends v,of the radiante and is'recessed to receive and retain the said ends, andtogform; a iiue in connection with the said slanting part ofv .1 the back wall for the Vconduction of waste gases `and heat tothe rear vent comprisingthe'registering recesses 53 and 56 inthe ,back-wall andthe'rear face of the hood. 'Y The back-wall is'seated in front of a retaining flange 57 on the'top of the frame mem- .ber2..'v f

' end"flanged and seated in' a recess 59in the Y hood;` The side edges of the jacket are seated in the columns just back of the lugs 46'v 58f-'is a sheet-metal jacket having its upper and VV54. .The jacket is ,"'spaced from the rear face of the back-wall and the hood and their opposing faces i is open atV the bottom and provided with several holes 60. A pipe connection 6l is secured in the jacket opposite the vent 53- 56, whereby the waste ygases may be coniiected toa chimney by suitable lengths of pipe. The jacket provides for a circulation of airso that .the stove may be set close .to a house-wall without danger of setting opposite direction. '2. ln a radiant tube, a' screw ksupporting one end of the tube and movable in one direction to hold the tube at one position and in thel opposite limiting the. movement of the tube in the direction to Vallow the tube to be moved u from said position,'a support for the rer maining end of the tube, and means for preventing longitudinal movement of the tube whenV thel screw is holding the tube in the said position, the support being sufficiently .short to--release the Jsaid remaining end of the Itube when theV screw has been backed 0E a short distance. 3. ln a radiant stove, a refractory back- .wall, radiante in front thereof, interlitting projections'and depressions on the opposing faces 'of the baclvwall and the radiante for interlocking` the i'adiants and the back-wall to prevent the radiants from,V moving laterally, .and :vertical grooves. between Vthe Aback-wall and radiante toV afford ventilation between Athe same.

'4. In a radiantstove, a frame, two hollow columns Y' supported thereby and open at theirV opposing faces, a back-wall having end portionsin the columns, a 'separable hood having end portions in the columns andresting on the bacs-wall,V and caps secured to Vthe' tops of thecolumns and overlying lthejsaid-end portions of the-back-v wallf j; 1 5. In a radiant stoveyaframe, av vertical column ate'ach end, vthe columns having their opposing facesV provided with vertical stove, a frame, aV mixer lOO slots',l a yrefractory backlwall` having end portionsfin the slots, radiants retained/at wall'spavced frointhe rear face ofthe back- Ywall* and 'having Wits ends seated in the-.said

slots andretained thereby.

their opposing faces provided with vertical slots, a refractory back-Wall havingv end portions in the slots, radiante retained at the front face of the back-Wall, and a ilue 5 Wall spaced from the rear face of the back- Wall and having its ends seated in the said slots and retained thereby and loosely supported by the frame.

7. In a radiant stove, a frame, a vertical column at each end, the columns having their opposing faces provided With vertical slots, a refractory back-Wall having end portions in they slots, radiants retained at rthe front face of the back-Wall, Va flue Wall spaced from ythe rear face of the back-Wallv and having its ends seated in the said slots and retained thereby, and a pipe connection carried by the flue-Wall.

In testimony whereof, I hereunto aiiiX my signature this 30th day of J une, 1923.
